<tml:action debounce ="true|false">
With the default debounce='true' it is not possible to execute an action twice without generating a new action link. This ensures that actions are not executed without user interaction for e.g. during a browser refresh or by using the browser navigation.
Combining a debounced action with AJAX type "norefresh" may be problematic, because the action link may not get refreshed after the action is called. Because of this the action link will only work once and be ineffective after that.
